Key Takeaway
A useful sample answers a defined question about fit, construction or materials. Give each round a version number, consolidate comments, and record exactly what is approved before the next stage begins.
A sample can look convincing on a hanger and still leave major production questions unanswered. Start by agreeing what the sample maker will deliver, what materials will be used and which decisions the round is meant to resolve.
Include front and back flats, construction details, a bill of materials and a measurement chart with diagrams. Specify the base size, target customer, intended layering, size range and care method. Add photographs for details that are difficult to communicate in a drawing.
For each point of measure, show the start and end positions, whether the garment is open or closed, and whether it is measured relaxed or stretched. State units and tolerances. A chest width is ambiguous if one person measures at the armhole and another measures lower down.
If you only have a reference garment, agree what should be retained and what should change. Check that you have the rights needed to use supplied designs and artwork.
| Sample | Main purpose | Limit to recognise |
|---|---|---|
| First prototype | Explore shape and construction | Substitute fabric may hide material behaviour |
| Fit revision | Check requested pattern corrections | One size does not validate grading |
| Size set | Assess the graded range | Bulk material differences can still affect results |
| Pre-production sample | Approve the production combination | Record any material or trim exceptions |
| Early bulk sample | Check actual line output | It must come from the relevant production run |
An established block may reduce the number of rounds. It does not remove the need to validate your fabric, measurements and intended fit. Avoid setting the bulk launch date on the assumption that every sample will pass first time.
Use a wearer whose measurements are recorded and relevant to the base size. Check the jacket over the intended underlayer, with closures open and closed. Photograph front, back and side views in a consistent position.
Ask the wearer to reach forward, bend the elbows, sit and use the pockets. Check neck comfort, sleeve rotation, across-back movement and hem position. Separate a measurement deviation from a design decision: increasing chest width may not solve restricted movement caused elsewhere in the pattern.
Identify the sample version and date. Give each issue a number, photograph, required outcome and owner. State whether a dimension changes and whether the change applies to all sizes. Resolve contradictory feedback inside your team before sending it.
For an illustrative comment: sleeve length measures 64 cm, the agreed target is 65 cm, and the requested result is 65 cm after finishing using the documented measuring method. These numbers are an example, not a recommended sleeve length. Ask the pattern maker to confirm the correction rather than prescribing unrelated pattern adjustments.
Have the team trial pressing, fusing and the proposed care process on the chosen combination. Record dimensional changes, surface appearance, bond performance and trim behaviour using agreed methods. Set processing conditions from the actual material and component guidance.
If substitute fabric is used for the first prototype, list which conclusions remain provisional. A successful fit in light calico does not prove that a coated shell or heavy wool version will behave identically.
Mark the sample approved, approved with defined exceptions, or requiring revision. Keep the approved sample reference, tech pack revision, measurement report and material list aligned. Confirm sample fees, courier costs, revision allowances and pattern deliverables at the start.
The private label specification guide covers the lining, rib, pocket and closure decisions that should be settled before bulk production.
Common Sourcing Questions
It depends on the design, existing pattern, material readiness and clarity of feedback. Agree the purpose and cost of each round rather than assuming a fixed number.
It may approve selected fit or construction decisions, but record the limits. Validate the actual production materials and trims before releasing the complete specification.
Manufacturing Journal
Define what private label includes before choosing a jacket block. Relabelling stock, adapting an existing pattern and developing a new pattern involve different costs, rights and approval work.
For patterned wool-blend jackets, approve fibre composition, handle, fit and specific check-matching points separately. Extra fabric depends on the repeat, width, pattern and size mix; a universal waste percentage is not reliable.
A low sewing minimum does not guarantee a small total commitment. Check minimums separately for each style, colour, fabric and trim, then calculate the cost of materials left over after the order.
